Hmmm? I recently compiled grass_trunk (as described in the wiki at 
<http://grass.osgeo.org/wiki/Compile_and_Install_Ubuntu>) and the GUI launches 
fine (under Kubuntu 64-bit). I have to note however that I rarely "work" with 
the GUI, so I only assume it works fine.

I have the following in ~/.bash_profile:
--%<---
# grass
export GISBASE=/usr/local/grass-6.4.0svn
export GRASS_GNUPLOT='gnuplot -persist'
export GRASS_WIDTH=640
export GRASS_HEIGHT=480
export GRASS_HTML_BROWSER=firefox
export GRASS_PAGER=cat
export GRASS_WISH=wish
export GRASS_PYTHON=python
export GRASS_MESSAGE_FORMAT=silent
export GRASS_TRUECOLOR=TRUE
export GRASS_TRANSPARENT=TRUE
export GRASS_PNG_AUTO_WRITE=TRUE
--->%--

(Actually I have configured my system as described in the following wiki-page 
<http://grass.osgeo.org/wiki/Working_with_GRASS_without_starting_it_explicitly>)

So, within from a grass7 session, any "d.rast" command (or other drawing) 
creates a file map.png (under the current working directory each time). And I 
can view it with any image viewer.

here you have to draw something, i.e. "d.rast SomeRasterMap"

I think "ximgview &" was suggested as a lightweight and quick viewer, that 
stays open like the (old-)x.mons (...good-bye Xmons :-( ). But this is I think 
irrelevant with this corruption, I think.

Do you launch grass in text-mode? i.e. "grass70 -text GRASSDB/LOCATION/Mapset" 
?
